IMPROVEMENT IN SEAL-LOCKS.

Specification forming part of Letters Patent No. [68,070, datedSeptember 21, 1875; application led March 20, 1875. i

will enable others skilled in the art to whichl it pertains to make anduse the same, reference being had to the accompanying drawing, and tothe letters of reference marked thereon, which form a part of thisspecification, in Which- A Figurel is a plan view of my improvedseal-lock. Fig. 2 is a vertical section of the same, with the lockingmechanism removed.`

Fig.3 is a detached sectional view of the locking mechanism. Fig. 4 is alike viewof the same, exhibiting the lacking-bolts in trans` is detachedside verse section, and Fig. 5 views of two of the locking-- bolts.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to a certain improvement in seal-locks, and itconsists of a case tting Within, and having boltsfor locking it in, asecond case, having-an internal ange, behind which the bolts fit, or areprojected, provision being made for the reception, and securing a sealover the key-hole, substantially as hereinafter more fully set forth.

In the annexed drawing, A refers to a case with the locking-bolts B B,which are projected through the same by springs O. The bolts B B areretracted by downward pressure on the key D, inserted through thekeyopening E in the top plate a ot' the case A, and pressing` at itsnotched end against inclined shoulders or projections b b on vthe bolts.In the said top plate a, on either side of the key-opening,is vanopening, c, 4to expose to vview the initials of the railroad cornpany,and number of the car on the seal inserted through alateral opening, c',in the said case, under Vthe said plate, when the lock isv A plate, -F,

used for securing a car-door. i hinged-to a stud or projection on thecase which receives'the case A, covers and protects the key-opening, &c.The inner portion of the case A being contracted, an annular lock it inplace.

jection, Gr, on the inner side of the receiving- V case H, behind whichthe bolts B B are projected when the case A is inserted therein to Aprojection, e,- is formed on the external circumference of the case A,and projects into an opening, h, of the receiving-case H, to prevent thecase A from turning when locked in place. The receiving-case H is rmlybolted in place, as shown', and is formed with an extension, t', throughwhich projects a -stout stud or projection, I, rmly bolted in place, andwhich permits of the attachment to the lock of a hasp, J, or othermeanspfor assisting in securing thedoor, a pin, K, passing transverselythrough the stud or projection I, With its head or enlarged portion,next'to thelock, for securing the hasp upon .the projection or stud.lhe opening h, above alluded to, permits of the withdrawal ot' the y pinK from the projection or stud I, to release the hasp when thelocking-case A is removed from its case H.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The locking-case A, having the springbolts B B b b, in combinationwith the receiving-case H, having the internal flange or projection Gr,substantially as and for the purpose set forth.

2. The locking-case A, having the springbolts B B, the lateral openin gcqior the insertion of a seal, and the openings c c, for viewing thesame, in combination with the receivingcase H G, substantially asdescribed.

3. The locking-case A, having the springbolts B B, and the projection@,vin combination with the case H G, having the opening h, substantiallyas and for the purpose set forth.

4. The combination of the locking-case A, having the spring-bolts B B,and receivingcase H Gr, having the opening h, with the pin K, stud orprojection I, and hasp J, or its equivaient, substantially as and forthe purpose set forth.

In testimony thatI claim the foregoing' as my own I afx my signature inpresence of two witnesses. y
